Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main protein, which softens and becomes tender during slow simmering.
- Tomatoes
- Form the acidic, flavourful base of the sauce and add moisture.
- Onion
- Softens and adds savoury sweetness to the sauce base.
- Butter
- Adds fat and richness to the onion as it fries.
The step that matters
Simmer very slowly until the meat is tender. Low, gentle heat lets collagen in the beef break down slowly without toughening the muscle fibres. Rapid boiling can leave the meat firm and dry while the sauce reduces too quickly.
